255307 ÷ 31 
Let's see how many times 31 fits into 255307.

Going ahead to step 1:
2 divided by 31 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 31

Let's proceed to step 2:
When dividing 25 by 31, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 31

Going ahead to step 3:
31 can be fit into 255 8 times, resulting in a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 248 away from 255, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 31

Let's proceed to step 4:
31 can be fit into 73 2 times, resulting in a remainder of 11.
The next digit of our result is 2. 
Result so far: 82.0
Subtract 62 from 73 to get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 31

On to step 5:
When dividing 110 by 31, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 823.0
If we subtract 93 from 110, we get 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 31

On to step 6:
31 goes into 177 5 times with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 8235.0
Deduct 155 from 177 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
31 goes into 220 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 8235.7
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
31 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 8235.7
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 31 is 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 8235.709
Subtract 279 from 300 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
When dividing 210 by 31, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 8235.7096
Deduct 186 from 210 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
31 can be fit into 240 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 8235.70967
Subtracting 217 from 240 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 12:
31 can be fit into 230 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 8235.709677
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 8235.709677 with a remainder of 1.3e-06.
